About DUCs

The Model 494.25 Digital Universal Conditioners (DUCs) condition AC and DC
transducers. You can use the same DUC to condition an LVDT (AC transducer)
for one test, and then to condition a load cell (DC transducer) for another test.

Model 494.25 DUCs are full range conditioners. This means DUCs accurately
cover the full scale of the transducer, which eliminates the need to select between
ranges for transducers. DUCs also provide the resolution and repeatability
required for measuring small percentages of their total range.
